NASA's James Webb Space Telescope finds most distant known galaxy      (via sciencedaily.com)     Original source 

Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.

The case of the missing black holes      (via sciencedaily.com)     Original source 

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

Planet hunters unveil massive catalog of strange worlds      (via sciencedaily.com)     Original source 

While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.

Potentially habitable 'exo-Venus' with Earth-like temperature discovered      (via sciencedaily.com)     Original source 

Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.

Complete stellar collapse: Unusual star system proves that stars can die quietly      (via sciencedaily.com)     Original source 

University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.

Hubble views the dawn of a sun-like star      (via sciencedaily.com)     Original source 

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3      (via sciencedaily.com)     Original source 

Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.

Researchers discover the universe's oldest stars in our own galactic backyard      (via sciencedaily.com)     Original source 

Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.

Astrophysicists discover a novel method for hunting the first stars      (via sciencedaily.com)     Original source 

A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
